The Atmospheric Monitoring Strategy for the Cherenkov Telescope Array

The Imaging Atmospheric Cherenkov Technique (IACT) is unusual in astronomy as the atmosphere actually forms an intrinsic part of the detector system, with telescopes indirectly detecting very high energy particles by the generation and transport of Cherenkov photons deep within the atmosphere. This means that accurate measurement, characterisation and monitoring of the atmosphere is at the very heart of successfully operating an IACT system. The Cherenkov Telescope Array (CTA) will be the next generation IACT observatory with an ambitious aim to improve the sensitivity of an order of magnitude over current facilities, along with corresponding improvements in angular and energy resolution and extended energy coverage, through an array of Large (23m), Medium (12m) and Small (4m) sized telescopes spread over an area of order ~km$^2$. Whole sky coverage will be achieved by operating at two sites: one in the northern hemisphere and one in the southern hemisphere. This proceedings will cover the characterisation of the candidate sites and the atmospheric calibration strategy. CTA will utilise a suite of instrumentation and analysis techniques for atmospheric modelling and monitoring regarding pointing forecasts, intelligent pointing selection for the observatory operations and for offline data correction.Comment: 6 pages.

RELIGIOUS MODERATION IN THE PERSPECTIVE OF MILLENNIAL STUDENTS IN ISLAMIC BOARDING SCHOOLS

This study aims to analyze how religious moderation is implemented at the Hidayatullah Islamic boarding school in Yogyakarta and the role of millennial students at the Hidayatullah Yogyakarta Islamic boarding school in realizing religious moderation. The research method used is descriptive-qualitative, which allows researchers to explore the understanding and meaning behind the development of religious moderation at the Hidayatullah Islamic Boarding School, Yogyakarta. Data was collected through interviews and direct observation at the Islamic boarding school. Research findings show that the Hidayatullah Islamic Boarding School implements religious moderation with the principle of "Tawasuth" as the main foundation, maintaining balance and preventing extremism among students. The principles of “Tawazun,” “Tasamuh,” and “Al-Adil” are implemented through various activities, creating an educational environment that supports moderation and avoids extremism. The role of millennial students at the Hidayatullah Islamic Boarding School is necessary, and they use technology to spread religious education, become mediators in religious dialogue, and socialize the values of moderation. Their creativity and humanitarian spirit help bridge the gap between religious traditions and the modern world. In this way, the Hidayatullah Islamic Boarding School becomes a place where religious moderation can develop and be realize

All Sky Camera for the CTA Atmospheric Calibration work package

The All Sky Camera (ASC) is a passive non-invasive imaging system for rapid night sky atmosphere monitoring. By design, the operation of the ASC will not affect the measurement procedure of the CTA observatory, for which we discuss its application in this report. The data collected should enable improved productivity and increased measurement time for the CTA observatory. The goal of ASC is to identify cloud position, atmosphere attenuation and time evolution of the sky condition, working within the CTA Central Calibration Facilities (CCF) group. Clouds and atmosphere monitoring may allow near-future prediction of the night-sky quality, helping scheduling. Also, in the case of partly cloudy night sky the cameras will identify the uncovered regions of the sky during the operation time, and define potential observable sources that can be measured. By doing so, a higher productivity of the CTA observatory measurements may be possible

Detection of ultra-high energy cosmic ray showers with a single-pixel fluorescence telescope

We present a concept for large-area, low-cost detection of ultra-high energy cosmic rays (UHECRs) with a Fluorescence detector Array of Single-pixel Telescopes (FAST), addressing the requirements for the next generation of UHECR experiments. In the FAST design, a large field of view is covered by a few pixels at the focal plane of a mirror or Fresnel lens. We report first results of a FAST prototype installed at the Telescope Array site, consisting of a single 200 mm photomultiplier tube at the focal plane of a 1 m$^2$ Fresnel lens system taken from the prototype of the JEM-EUSO experiment. The FAST prototype took data for 19 nights, demonstrating remarkable operational stability. We detected laser shots at distances of several kilometres as well as 16 highly significant UHECR shower candidates.Comment: Accepted for publication in Astroparticle Physic

Management of melanoma metastases in the brain

The basic principle for the diagnosis of melanoma metastases in the brain should be the management of multidisciplinary teams including at least a neurosurgeon, radiotherapist and clinical oncologist experienced in the treatment of melanoma and melanoma metastases in the CNS. Detection of brain lesions is associated with poor prognosis; metastases in the brain are the cause of death in 20–50% patients, and symptomatic tumours are a direct cause of death in about 90% patients. Treatment of melanoma with CNS metastases may include local management and/or systemic and symptomatic treat­ment. In the last 5 years, 10 new advanced melanoma drugs have been registered in Europe. Two-drug therapy anti-PD-1 and anti-CTLA-4 (nivolumab with ipilimumab) is the treatment of choice for asymptomatic melanoma metastases in the brain, while in the presence of BRAF mutations and asymptomatic metastases systemic treatment with BRAFi and MEKi may be the first-choice treatment

Stymulacja rdzeniowa w leczeniu dławicy piersiowej

Spinal cord stimulation (SCS) is a well known method of treatment used worldwide since the 80’s of the last century. High efficiency of SCS was observed in the treatment of various types of pain. Promising clinical results were observed in the treatment of patients with refractory angina (RA). Reduction of angina attacks reduces doses of medications and improves quality of life. SCS efficacy in RA is comparable to that observed among patients treated with cardiac surgery (CABG) and percutaneous coronary intervention (PCI), with lower risk of complications and rehospitalisation. SCS is more cost effective compared to CABG and PCI. SCS might be considered for patients who did not respond to reperfusion therapy. The mechanism of action in RA is not well understood. It is known that SCS reduces the activity of the sympathetic nervous system, by which improves the coronary perfusion and oxygenation of the heart muscle. It is important that SCS does not mask the pain related to the infarct. Kardiol Pol 2011; 69, 4: 383-38
